Kaillie Humphries started small on tattoos -- a Canadian bobsled on her leg -- when she was 18 to celebrate first making the national bobsled team.

Now, there's not much room left for ink although she's promised her coach Stuart McMillan that he can design a small tattoo probably to go on her back if she wins a third gold medal at the 2018 Winter Olympics.

Humphries explains

"Everything has a meaning. I have my parents (on her arm). Both are still alive and well, but I'm away a lot and have been since I was a kid. So having them with them is very important. The horse is for my sister. I have a key for my other sister on the other side.

"The left sleeve embodies me more as a whole. The clock representing time, my fascination with it, I'm judge on it but too much time, not enough time. All my thoughts and doubts. Rise and rise again until lambs become lions (lion tattoo), to understand to need give me. The eye meaning focus or window to the soul.

"I have peony flowers with a jewelry box. My grandfather and my uncle have both passed away and my uncle godfather had made me this wooden jewelry box the last year he was alive. That's for him. And my grandpa used to grow peony flowers in his front yard.

"I have both Olympics medals tattooed on my back. Do not fear for I am with you (Bible verse). The crown, every woman deserves to be a princess or a queen every so often so we got that. The dream catchers. Because you loved me was another saying my grandmother used to say, and I put it in Icelandic.

"Overall just different meanings of people that have shaped or created who I am. Goals, things I've overcome, things I've learned about myself. Dreams, aspirations, my family, people that make me who I am. It's a collage of who I am until this point. It will keep growing. I promised Stu a piece if we win again. He gets to decide. We made this pact a couple of years ago. I want him to be represented along with my medals because he's a big reason why I have these. He wants to stick his face on there, which I'm not too sure about."
